To ally/1mm it my concern:

'Be it' known that I, JULss LOUVE'L, of Montrouge, Seine, France, haveinvented :1 Device for Automatically Stopping the Disks ofTalking-Machines, of which the following is a specification.

This invent-ion relates to the automatic stopping of the disks oftalking machines provided with a needle or a sapphire when theperformance is finished, this stopping arrangement being applicableincases where the disks employed bear a record beginning near the centerand finishing near the circumference. \Vith this object, the recordisextended by a curved or' straight groove or embossment which causes theneedle or the sapphire to move outside of the disk; the sound arm thenfalls on to a rod and weight actuates a brake which stops the disk. i

Figures 1 to 9 illustrate two different forms of the device employed.Fig. 1 is a plan of a talkin machine provided with the automaticstopping device. Fig. 9. is a plan of the stopping apparatus. Fig. 3 aside view of the same. Fig. 4 an end elevation. Figs. 5 to 9 illustratea modified form of the device. Fig. 5 is a plan of a machine providedwith a stopping device; Fig. 6 is a side view of the brake mechanism;Fig. 7 a

.plan of;the same; Figs. 8 and 9 being respectively an elevation and aplan of a dit ferent form of the brake.

For the purpose of insuring the automatic stopping of the apparatus, thedisk abearing the record has, following the record, a curved or straightgroove or embossment I); along which the needle or the sapphire. carriedby the diaphragm 0 arranged on the sound. arm (I having completed itstraveL.

that is to say finished the reproduction of the piece. is held by thesapphire in the last spiral of the record while the disk continues torotate until the spring is completely relaxed.

Specification of Letters late nt'd P t t a "I Application filed March18, 1910. Se;

*ceires: the Fso'und arnr' tl -wli-eii Etlipieceis The automaticstopping'acc di invention is etiecteda's' la'llo'ws' terminating in theform ot-a i position; ;a pedestal-7' having;

finished. the arm (I being moved outside by the disk .1, under theaction of the curve I) that runs to the outer rimof the disk and alongwhich the sapphire or the needle must move. atlthe end of the record.The sound:

arm (Z drops on to the T partof the'ro'd i and by its weight lowers thatrod. This latter exercises pressure on another rod k termimifing in anangular piece which actriates a lever Z. To this levers smallconnecting-pod m is attached which terminates on thezone hand in a pivotand on the other hand is connected with the rod f and imparts theretothe motion for effecting stopping, similar to that which would have beenimparted with the finger. The leverm' the is flexibly connected andfixed at n on a support 0 which likewise supports the lever-Z.

To one of the ends of the connectin rod a."

spring 9 is attached which is put-un er tension of a screwnq held by asupport r-and insures the starting of the apparatus. The regulating ofthe throw of the lever l'is effectcd'by a. small screw slmounted on thelever la. y p

In the simplified device shown in Figs. 5

to 7 the brake action is effected on the outer rim of the disk-carryingtable t. In these 1.5 the brake is represented as in contact with thedisk carrying table. The de vice comprises a pedestal j, formed with asocket in which the rod i is engaged the upper end or head of which isin the form of a T and receives the sound arm at the required moment.The lower part Qf this rod 5 rests on a small lever u pivoting at 0 onthe bins of the pedestal j. The free end of the lever 11- rests on apiece X pivoting at X and constituting the brake. .A :spring y -pushesthe brake-piece X back so as to allow the free rotation of thedisk-carrying table t during the performance. When the performance isfinished, the curve 6 leads the sapphirc or the needle outside of thedisk a, the sound arm t falls on to the T-head of the rod 1' and thebrake X acts onthe-rim of the table 2, causing it to cease" rotating.

In the device as in Figs. 8 and 9, the sto carries the rod 11 as in thedevice described above. vThis rod 2' bears, at the required moment, on alever 41 carrying a brake shoe 2 a rotatable disk-carrying table,a-record whichacts on the under shrface of the table t. The part of thelever-y where the brake shoe 2: is placed forms a counterweight andraises the rod i while the apparatus is in I disk carried thereby, asound arm, and a needle. carried. by the latter, of a brake de- -vice-"comprising an arm adapted' to be brought into contact with the table,and a second arm arranged to support the sound arm when the latter hasbeen moved laterally to cause the needle to bemoved off of the recorddisk, said second arm being operated by the weightof the soundv arm toeffect the operation of the first arm and stop the rotation of the tableand disk.

In testimony whereof I afiix my signature in presence of two witnesses.v J ULES LOlLl'VElZ. "Witnesses:
